摘要：
The consistent video quality and encoding latency due to buffering are two important aspects in designing rate control scheme for the application of real-time video coding system. To well balance these two contrary objectives, we firstly analyze the constraint of buffer latency and the definition of a "consistent" video quality. Then a window-based rate control scheme is proposed with one window for controlling the rate and latency, while the other window for optimizing video quality. By applying low complexity frame level rate-distortion model in the testing sequences, our proposed method shows excellent performance in balancing the encoder buffer latency and optimized video quality. Besides, this one-pass rate control scheme is highly practical for the real-time video coding application.
